摘要
目的:观察腹腔镜肾切除术麻醉期间腹膜后间隙CO2气腹对呼吸循环的影响。方法:择期手术全麻患者15例,ASAⅠ~Ⅱ级,静脉谤导后作气管内插管,机控呼吸,并维持潮气量8ml/kg,监测MAP、ECG、CVP、VT、PEAK、SPO2、PetCO2和动脉血气分析。分别在控制呼吸5min、气腹前、气腹后10、30和60mln时记录各项监测数据。结果:充气前后SPO2和PaO2均无明显变化(P〉0.05),VT减幅不大,PEAK轻微升高(P〉0.05),HR和MAP无明显变化(P〉0.05),CVP明显升高(P〈0.01)。PetCO2和PaCO2升高(P〈0.01),PH值下降但仍在正常范围(P〈0.01)。结论:全麻下机控呼吸时,腹膜后CO2充气对呼吸循环功能影响较轻,维持足够的通气量可避免因CO2经后腹膜吸收造成的高碳酸血症。
Objective: To observe the effect of respiration and circulation to use the CO2 - Pheunoperitoneum in retropiritoneal space during the anesthesia in laparoscopin nephrectomy. Method: To choose the patients of general anesthesia 15 in a lot, ASA Ⅰ -Ⅱ, induction of anesthesia to endotracheal intubation, breathing by respirator, keeping tidal volume on 8 ml/kg , monitoring the MAP, ECG, CVP, VT, PEAK, SPO2, PetCO2 arterial blood gas analysis in 5,10,30 and 60 minutes. Result: To compare filling gas with no gas , no difference between SPO2 and PaO2 ( P 〉 0.05 ), no obiously change in VT and PEAK ( P 〉 0.05 ). So does in HR and MAP ( P 〉 0.05 ), CVP, PetCO2 and PaCO2 inproving obviously ( P 〈 0.01 ). Conclusion: To fill gas ( CO2 ) in retroperitoneal space during general anesthesia, there is little influence to the respiration and circulation. Keeping enough ventilatorv. Capacity can avoud the hypercaonia in restrooeritoneal soace.
